LAPPET FOR SPINNING AND LIKE MACHINES.

raoaoae.

To all whom it may concern Be it known that we, J osnrrr SHAW GAUNT andHARRY DYSON, of Manchester, in the county of Lancaster, England, haveinvented certain new and useful Improvements in or Relating to Lappetsfor Spinning and like Machines, of which the following is aspecification.

The object of the present invention is the improvement of lappets andthread guides for spinning and like machines and more particularly toprovide improved means of securing firmly in position a removableeyelet, which when out by the yarn or thread can be easily removed andreplaced by a new one.

According to this invention a porcelain or other suitable eye is held inposition by means of a resilient bifurcated holder secured to the lappetby a bolt in the usual manner. The eye is suitably formed to fit betweenthe two members of the bifurcated holder and the parts are so arrangedthat the eye is firmly gripped by the said members being forced togetherwhen the holder is secured by the bolt to the lappet. The eyelet may beso formed that the two members of the holder must be pushed apart beforethe eyelet can be removed aswill be further described.

The forward portion of the bifurcated holder can be formed with splayedprojections adapted to guide the yarn into the eye and also withlaterally extending slots adapted to prevent the yarn from flying out.

The lappet may be secured to the lappet board in any convenient manner,for exam.- ple, by hinges with elongated holes to per- Init lateraladjustment.

In order that the invention may be better understood a sheet of drawingsis appended in which Figure 1 is a plan view of the bifurcated holderand the lappet.

Fig. 2 is a section on line 2-2 of Fig. 1, and shows the front part ofthe lappet.

Figs. 3 and a show the removable eyelet in sectional plan and elevation.

Fig. 5 is a view similar to Fig. 2, showing a modification.

The same reference characters indicate the same parts in all of thefigures.

1 represents a laterally compressible bifurcated holder, formed with asuitable circular opening 2, the sides of which form jaws adapted toreceive and grip the porcelain or Specification of Letters Patent.Patented App, 29, 19 19,

other eyelet l2; splayed wings 3, to facilitate the entrance of theyarn, and notches 4, to prevent the yarn from flying out again. Theholder is provided with a positioning member, here shown as a recess 5,at the inner ends of said gripping-jaws. The eyelet 12 is provided withthe usual yarn-receiving slot 13 at one side, and is provided with acompleniental positioning member, here shown as a projection 5 adaptedto enter the recess 5 and prevent the introduction of the eyelet exceptin the correct position, said projection being diametrically oppositethe slot 13. The bifurcated holder ispreferably made of suitablethickness to fit in a corresponding groove 1", in the peri hery of theeyelet. In the lappet 7 a suita le slot 7 a is formedv to receive a bolt8, said bolt having a head and a nut adapted to exert clamping pressuresimultaneously on the lappet and the holder. The rear portion of theholder 1 is provided with a slot 6, through which the bolt also passesso that the holder can be adjusted inward or outward on the lappet sofar as the limits of the slot 6 permit. The holder 1 is so formed thatits natural spring is not necessarily sufiicient to grip the eyelet withthe requisitefirmness until the holder is fastened to the lappet by thebolt 8. As shown by Figs. 1 and 2, the edge portions 7 of the lappet arebeveled to form an angle greater than a right angle with the sides ofthe lappet, and the edge portions 9 of the two members of the bifurcatedholder 1 are correspondingly beveled. When the bolt 8 is loosened theholder can be adjusted inward or outward as required, and as soon as thebolt is again tightened, the bifurcations of the holder are pressedtogether by the beveled edge portions and firmly grip the eyelet, theholder being therefore simultaneously secured to the lappet in the required position and caused to grip the eyelet. Other forms than thatshown in Fig. 4: may be adapted without departing from the spirit of theinvention. For instance, the bolt 8 may be provided with a washer 10formed with tapered faces 10 to engage correspondingly tapered edgeportions 9 of the holder, as shown in Fig. 5.

It will be seen that the wings 3 are spaced apart to form a slot orpassage permitting the entrance of the yarn into the eyelet, and thatthe notches 4c are obliquely arranged relatively to said passage andopen into the latter. It will also be seen that the positioning meansincluding the recess 5 and the projection 5, are arranged to hold theyarnreceiving slot 13 of the eyelet in alinement with the thread{passage formed by the wings3.

Claims:

1. In combination, a lappet, a bifurcated laterally compressible holderhaving opposed eyelet-gripping jaws, and a headed bolt having anadjustable nut and adapted to exert clamping pressure simultaneously onand detachably connect the lappet and holder, holder-compressing means,actuated by said pressure, being provided for laterally compressing theholder.

2. In combination, a lappet having beveled edge portions, a bifurcatedlaterally compressible holder, having opposed eyeletgripping jaws andbeveled edge portions complemental to the beveled edge portions of thelappet, and clamping means adapted to exert pressure simultaneously onthe lappet and holder and at the same time cause said beveled edgeportions to cooperate in laterally compressing the holder, and causingsaid jaws to grip an eyelet.

'3. In combination, a lappet having bev eled edge portions, a bifurcatedlaterally compressible holder, having opposed eyeletgripping jaws andbeveled edge portions complemental to the beveled edge portions of thelappet, and a headed bolt having a nut and adapted to exert clampingpressure simultaneously on the lappet and holder and at the same timecauses said beveled edge portions to cooperate in laterally compressingthe holder, and causing said jaws to grip an eyelet.

4. In combination, a bifurcated eyelet formed to project therefrom, saidholder having eyelet gripping jaws, an eyeletpositioning member at theinner portions of said jaws, and wings projecting outwardly from thejaws, said wings being spaced apart to form a threaded passage, and aneyelet formed to be gripped by said jaws and having a, yarn-receivingslot at one side, and a positioning member complemental to thefirst-mentioned positioning member and diametrically opposite said slot,whereby the eyelet slot is held in alinement with said thread passage.

5. In combination, a bifurcated eyelet holder adapted to be secured to asupport and formed to project therefrom, said holder havingeyelet-gripping jaws. an eyeletpo sitioning member at the inner portionsof said jaws, and wings projecting outwardly from the jaws, said wingsbeing spaced apart to form a thread passage, and an eyelet formed to begripped by said jaws and having a yarn-receiving slot at one side, and apositioning member complemental to the first-mentioned positioningmember and diametrically opposite said slot, whereby the eyelet slot isheld in alinement with said thread passage, said wings being providedwith oblique notches opening into said thread passage and adapted toprevent the yarn from flying out.

In testimony whereof we have affixed our signatures in presence of twowitnesses.
